Chronographing lugers

[stressed]

I know this is not the original topic of this thread but I wanted to add it. These are 3 standard pressure casings of different brands fired through my Luger. From left to right - Federal, Magtech & Blazer. They all exhibit a slight bulge. (Don't have a steel case for comparison, as I won't shoot it through a luger)

It's hard to see with the flash, but plain as day when looking at them in person.

Actually, I did this about 2 months ago and was impressed by the velocity gain. I took my 4 in 1936 Luger and my 1917 Arty to the range and fired a few rounds across my ProChro chronograph
( Its always been accurate and repeatable ). The loads were 6.2gr of Power Pistol, 125gr Hornady HAP bullet and Win. primers. The 4 incher was doing around 1180-1190, and the rounds out of the Arty were averaging 1305 !
Now, these loads were made up for my Browning Hi-Power, and are probably a little too stiff for regular use in a Luger, but it does show those extra 4 inches do make a difference.

Hi,

I also own a Hi-Power and enjoy shooting it very much.

I agree that 6.2grs of Power Pistol is a bit hot for a Luger. My accuracy load for the 124gr bullet is 5.4grs. It is a full power load and is highly accurate.

For my LP-08, I have settled in on slower powders than Power Pistol for tighter groups.

So far, for P-08 Luger shooting, Power Pistol has been the very best powder I've worked with to date. Later this Spring, if I can locate any powder to test, I'm going to test just about every medium/slow powder I can find for function and accuracy.

Hi,

Do the bulges go all the way around the bases of the cases, or are they lopsided on one side?

Also, the Luger has a stepped chamber (slightly bottlenecked near the top of the brass). Are you taking this fact into account?

Sieger, do you have any experience using AA #7 in longer barreled Lugers? Ive got a good bit I bought a while back to use in 7.62 Tokarev and 7.63 Mauser, but haven't really done anything with it in 9mm.

Hi,

For the LP-08, my best two powders have been 3N37 and Blue Dot.

With 3N37, I can regularly shoot three shot groups into about .5 inches at 25 yards.

With Blue Dot, I can regularly shoot three shot groups into about 1.0 inch at 25 yards.

Both of these groups were shot with the stock attached and rested over a sandbag.

I've never tired AA#7, but would really like to. The problem now, as you know, is simply finding any powder to buy.
